Hang on…. The structural engineers got an update to the aero surface? This deserves a slow clap… ???????? https://t.co/iEeOOWN5CP

If you want to see how tufts react in a stall condition on a wing, then check out the video below. A great illustration of how this simple visual device can show an instantaneous change in the flow field. So simple, yet so effective.

Nominal 1 G stall. Constant chord, constant thickness, no washout ...

I love how you can really see the intent of the aero elements from front to back.

The front wing and the aero appendages all workings to generate local load, and pre-condition the flow (blue) to interact with the front tyre wake.

The front tyre disruption is quite problematic, https://t.co/mqw38Qh07l

This excellent photo by @MateuszMrz8 shows another way of visualizing the air flow that differs from the flow visualization paint.

These are tufts. The small tufts (light string) moves as the air drags it along. The lower attached device is likely a camera that is recording the https://t.co/v19hx22KJZ

Slick update! So why make a stepped bib edge profile like this?

Firstly, this extended bib acts like the rest of the floor generating downforce due to ground effect. That means directly under this bib is very low pressure. Here also the bib vane is now extended back which could https://t.co/Zf7LDAc6ej

RBR will struggle with balance for the rest of the year. The issues is in the chassis and they've gone and done it again. Won't be resolved until next year unfortunately when a whole new chassis can be developed. The problem isn't aero. It's how the aero and the chassis are

Why would RBR be looking at the flow structures behind the front tyre?

Well, for this race RBR have updated the front wing for downstream flow conditioning. More specifically the dive plane and end plate geometry. This outboard aero device is key to helping to direct air and https://t.co/IxiTKCkG9V
